Hi,

It really depends on what happened in those 4+ years, if you had any interruption in the residence cards, what kind of cards you had, etc. Normally it would be at 5 years, and you don't have to do much I think, I will do it soon and they asked me: copy passport , proof income last 3 months and proof health insurance (max. 6 months old). But I would make an appointment with the immigration office at your city and just ask them, they will look at your dossier and tell you exactly when to ask for it and what to bring.

good luck
